E.I. DuPont de Nemours & Co. on Tuesday reported net income of $452 million, or 48 cents per share, for the period ended Sept. 30. That’s up from $367 million, or 40 cents per share, for the same period a year ago. In last year’s quarter, the expiration of patents in DuPont’s pharmaceuticals segment lowered net income by 13 cents per share.

Excluding one-time items, including costs associated with its acquisition of Danish food additives maker Danisco, DuPont reported earnings of 69 cents per share. That topped the average analyst estimate of 56 cents.
